7. Installation & Maintenance

  1. Power OFF the XRC controller and lockout/tagout.

  2. Remove the controller’s front cover.

  3. Insert JANCD‑CU20 into an empty 3U slot; secure with two screws (0.6–0.8 N·m).

  4. Connect CN1–CN5 cables; ensure tight, secure connections.

  5. Power ON; run I/O self‑diagnosis via the teach pendant to verify operation.

Maintenance: Inspect connectors annually; keep free of dust and moisture.

8. Troubleshooting (XRC Fault Codes)

  • E21: I/O board power failure → Check 24 V DC supply and CN1 wiring.

  • E22: I/O communication error → Verify CN4 bus cable and CPU board.

  • E23: Digital input short circuit → Inspect field wiring and sensors.

  • E24: Analog output overload → Check load impedance and wiring.
